- Followed and built upon CLuaRainbob changes
-> Attenuation has been changed into sound level and is more intuitive
-> Added DSP (digital signal processing) and a convar for it
-> Added send to stream radio button
-> Put 3 buttons into one category in the menu
-> Sound presets are now only present if you have mounted the content they're part of.
-> Removed some useless code
-> other things

- recipient filter is now updated per loop

- Add sound level attenuation option
- Add editable entity properties in context menu

- no visible change

-

- Change convar names that contained 'mv_soundemitters' (it's now written 'mv_soundemitter')
- Add convar to limit sound level of any sound 'sv_mv_soundemitter_max_sndlvl'
- You can now see the sound level (in decibels, dB) when looking at a sound emitter

- Sound emitter update function now converts "0" and 0 to false for bool properties. This fixes the incompatibility issue with older sound emitters.

- Bug fix 2: sound emitters always used toggle due to syntax problem

- Bug fixed (GetClientInfo -> GetClientBool)

Revert to version just before: problem with duplication and booleans. Bug not fixed.
- Update: this bug was present for quite some time and was due to GetClientInfo being used instead of GetClientBool, but also because booleans were saved as "0" before.
